At a building site, a 3-m-thick clay layer is overlain by a stratum of sand and bounded on the bottom by rock. Calculations indicate that foundation settlement due to primary compression (consolidation) will be 40 mm. The coefficient of consolidation for the clay is 0.055 m2/month.(a) Determine the time period for 90 percent of the primary compression settlement to occur.(b) Indicate the settlement expected one year after construction.

Consolidation parameters

Consolidation is the process of expulsion of pore water present in the voids of soil solids under the pressure of the applied load. This is a quick process in the case of coarse-grained soils since the permeability is high due to the presence of more voids, while it is a slow and gradual process in the case of clayey soil as the permeability of clay is less. An example of consolidation is the settlement of soil under a building due to the load coming from the building.
